. 2 Claims. l I

The present invention relates to a window frame and more particularly toa window'of the type commonly employing double hung sash.

In the double hung type of window frame now in common use the stiles areprovided with boxes in which run counterweights which are connected tothe sashes for counterbalancing them and holding them at selectedpositions in the window opening. The use of counterweights requires themounting of pulleys in the upper reaches of the stiles and the use offlexible members trained over the pulleys and connected to the counterweights and sashes. In the ordinary window frame the stiles are alsoprovided adjacent their lower ends with access openings through which aweight is accessible for service should a flexible member to which theweight is attached become broken. Such access openings are normallyclosed by separate panels held in place by fastening means whichfrequently become so covered by paint as to render it almost impossibleto remove .the panel when the weight covered thereby becomesinoperative. Moreover, due to the fact that the sashes must slide freelybetween the stiles, the stops and the parting strips in order for thecounterweights to properly function, gaps between the frame and thesashes result, ,and these gaps are not only not weathertight but willpermit a sash to rattle in its frame.

The primary object of the present invention is to so. construct a windowthat the sashes are not only weathertight but which willnot rattle.

Another object of the present invention is to hold the sashes inselected positions in their frames without the necessity of employingcounterweights, counterbalancing springs or the like.

A still further object of the present invention is to facilitate theremoval of the sashes from a window frame for cleaning, glazing, repairsor for any purpose desired by the user. v

The above and other objects may be attained by employing this inventionwhich embodies among its features, shoes mounted adjacent a stile andbetween the stops of the frame of a double hung window for movement in apath which lies perpendicular to the stile, springs mounted between thestile and the shoes for yieldingly urging the shoes to move in said pathaway from the stile and means carried by the shoes and extending throughthe stile for holding the shoes against movement by the springs.

Other features include screws carried by the shoes and extending throughthe stile and strips carried and threadedly engaged by the screws andbearing on the sides of the stiles remote from the shoes to form stopsby which the movement of the shoes is arrested.

In the drawings:

Figure 1 is a rear elevational view of a window frame embodying thefeatures of this invention.

Figure 2 is an edge view of said window frame.

Figure 3 is a horizontal sectional view taken substantially on line 33of Figure 1, the upper sash being shown in slightly lowered position.

Figure 4 is an enlarged sectional view through the shoes and strips.

Figure 5 is a fragmentary enlarged side view 0 a screw, and

Figure '6 is a perspective view of a spring retaining ring employed tohold a, screw in a. shoe.

Referring to the drawing in detail a window frame designated generallyIt] comprises a sill l2, a lintel I4 and stiles l6 and I8. The stile I6is of conventional form and includes outer and inner stops 2!] and 22between which is supported a conventional parting strip 24 which defineswith the stops 28 and 22 runways 26 and 28 for the outer and innersashes 30 and 32 respectively.

The stile I8 is provided with outer and inner stops 34 and 36respectively but unlike the stile IS the space defined between the stops34 and 36 is of somewhat greater depth than the space defined betweenthe stops 20 and 22. Extending through the stile i 8 are horizontallyspaced rows of vertically spaced openings 38 and 40.

Mounted in the space defined between the stops 34 and 36 adjacent thestile I8 is a shoe designated generally 42 which comprises an elongatedrectangular body 44 of wear resistant fiber carrying adjacent onelongitudinal marginal edge an outstanding flange 46 which when the shoeis in place forms a parting strip between the sashes 30 and 32. Formedin the body 44 is a longitudinal row of openings 48 which increase indiameter as they approach' the side of the body adjacent the flange 46for the reception of supporting and guide members 50 which in thepresent embodiment of the invention take the form of flat headed screws.The openings 48 in the body 44 align with the openings 38 in the stileIt so that the guide members 50 may pass through the openings 28 andenter a stop strip 52 which is disposed against the side of the stile IRremote from the shoe 42. A compression coiled spring 54 encircles eachguide member 40 between the stile l8 and the shoe 42 to exert pressureon the shoe and urge it away from the stile l8. The body 44 and flange4B define a guideway 41 adjacent the stile I8 for the sash 32.

Mounted in the space defined between the stops 34 and 36 and the stile[8 adjacent the shoe 42 is a shoe 56 which comprises an elongatedrectangular body 58 of wear resistant fibrous material which like thebody 44 is provided with conical recesses 60 for the reception ofsupporting and guide members 62 which like the members 50 comprise flatheaded screws. These supporting and guide members 62 extend through theopenings 60in=the stile l8 and enter a st'oip grip 64 which like thestop strip 52 bearsagains't the side of the stile I8 remote from theshoe 55.

A compression coiled spring 66 encircles each' supporting and guidemember 62 between'ttie f stile l8 and the shoe 56 to yieldingly urge theshoe 56 away from the stile l8. shoe 56"56- "operates with the stop 34and flange-Min defining a guideway 68 for the sash 30.
